[0026] See also Figure 1 and Figure 2 As shown, when the operator needs to replace the tool, he can remotely issue a field tool command. Specifically, he can use mobile phones and other electronic products to transmit the command to the controller in the device. After receiving the command, the controller controls the vehicle body 1 to move according to a predetermined route and move to a predetermined position. The staff can take out the required tools from the tool cabinet and place the replaced old tools in the tool return bin 5, thereby realizing the replacement of tools without leaving the workstation, reducing the risk of the machine tool colliding with the machine and not being able to stop in time during the existing process of leaving the workstation to take the tools.

[0027] In this embodiment, the vehicle body 1 can use a motor as a power source, and accordingly should also have a mobile power supply to provide power for the motor. Rollers driven by a motor are installed at the bottom of the vehicle body 1 to achieve movement, so as to facilitate moving 2 to a predetermined position. Here, the mobile power supply can also provide power for other components.

[0028] In other embodiments, the tools in the tool cabinet 2 can also be automatically selected. For example, when a specific model of tool is required, the tool disc mechanism or tool magazine in the tool cabinet 2 can move the required tool to the tool retrieval door 4, and the operator takes out the tool from the tool retrieval door 4. There is no need for manual selection, thereby improving efficiency. It should be noted here that the tool disc mechanism used for selection can adopt the tool magazine rotating structure or conveyor chain structure in the existing machine tool. The tool magazine structure here is the existing technology, and technical personnel in this field can choose it according to their needs, that is, only a structure that can transport the specific tool to the outlet is required, and no specific restrictions are made here.

[0029] Here, the opening method of the knife return bin 5 can be selected to be automatically controlled by the controller or manually opened, which can be selected according to needs. It should be noted here that the automatic opening method of the knife return bin 5 can be selected by referring to the principle of the existing express automatic storage and retrieval cabinet.

[0030] A camera 8 for collecting real-time information about the surrounding environment is installed on the top of the tool cabinet 2 , and the camera 8 is electrically connected to the controller; there are two cameras 8 , which are installed at both ends of the top of the tool cabinet 2 .

[0031] In this embodiment, the camera 8 is used to collect image information such as objects and portraits around the walking path in real time, and the collected information is transmitted to the controller. The controller analyzes the information collected by the camera 8 to avoid people and objects on the route to prevent collisions. For example, when there are people on the walking path, a prompt can be issued or the vehicle can stop moving forward or change the route or make a detour. The specific situation can be set as needed and is not limited here.

[0032] The tool compartment door 3 is also equipped with a display 6 and a barcode scanner 7 for scanning codes.

[0033] When the AGV moves to the predetermined position according to the route, the operator can scan the barcode with the barcode scanner 7 to confirm the specific identity of the operator. After the specific identity of the operator is verified, the controller determines the tool required by the operator. At this time, the tool disc mechanism in the tool cabinet 2 rotates to select the corresponding tool and transports the specific tool to the tool retrieval door 4, so that the staff does not need to select it, which is convenient and fast; the tools in the tool cabinet 2 are counted through the display 6, and the tool model of the corresponding tool station can also be displayed. The display 6 can choose a touch-screen display, and the corresponding instructions can be directly operated by touching to take out the corresponding tool.

[0034] The surface of the tool compartment door 3 is provided with a transparent plate 9 for observing the interior of the tool cabinet 2 ; the tool conveying process inside the tool cabinet 2 can be visually observed through the transparent plate 9 .

[0035] The tool compartment door 3 is also provided with a door lock 14 for opening or closing the tool cabinet 2 compartment door.

[0036] When the tools in the tool cabinet 2 need to be supplemented, the tool compartment door 3 can be opened by inserting a corresponding key into the door lock 14 to supplement the tools in the tool cabinet 2 .

[0037] A plurality of evenly distributed distance sensors 12 are disposed on the circumference of the shell of the vehicle body 1, and the distance sensors 12 are electrically connected to the controller.

[0038] The distance sensor 12 is used to sense the surrounding mechanical energy and obtain signal feedback to prevent collision with people or objects. The sensing distance of the distance sensor 12 can be set as needed and is not limited here.

[0039] The vehicle body 1 may be provided with an anti-collision strip 11 on its circumference. Objects or personnel may directly collide with the vehicle body 1 through the anti-collision strip 11 around the vehicle body 1, causing personal injury or damage to the vehicle body 1 when colliding with an object.

[0040] An antenna 10 is installed on the top of the tool cabinet 2, and the antenna 10 is electrically connected to the controller.

[0041] The antenna 10 can wirelessly receive remote commands or send corresponding information to expand the scope of use.

[0042] A charging port 13 is provided on one side of the bottom of the shell of the vehicle body 1; when the mobile power source is out of power or has low power, it can be charged through the charging port 13. In this embodiment, when the power of the mobile power source is reduced to a certain value, the charging command can be automatically started. Specifically, when the power drops to a predetermined value, the controller controls the vehicle body 1 to move to the charging position, and connects the charging port 13 to the charger along a predetermined trajectory and with the assistance of the camera 8 and the distance sensor 12 to realize automatic charging. After charging is completed, the vehicle body 1 drives the tool cabinet 2 to move to the standby position to wait for operation instructions.
